KNITTING-MACHINE NEEDLE AND LEVER FOR HOLDING SAME.

SPECIFICATION forming part of Letters Patent No. 781,654, dated February7, 1905,

Application tiled June 2, 1904. Serial No. 210,806.

To It nrhmm it may concern:

Be it known that I, HARRY A. Housmmn, a citizen t the UnitedStates,residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement inKnitting-Machine Needles and Levers for Holding the Same, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, which form a part of this specification.

My invention has for its object certain improvements inknittiiig-machine needles and levers for holding the same, such as areshown and described in Letters Patent issued to me October 18, 1892, No.464,737, in which each needle rests between the jaws of a lever, theneedle being supported in line with the knitting-cams, but resting on aledge extending around from the knitting-cams. By rocking a lever itsneedle is moved by contact with the jaw inward out of line of theknittingcams and is supported in that position by the end of the needleresting upon a ledge on the lever. In practice there is a tendency inmoving these levers to throw these needles from operative position toinoperative position, and vice versa, and while in inoperative positionfor the needle to move upward, due to jar or otherwise, and thusreleasing the loop from the latch, which is liable to close, and whenagain operated to miss a stitch, leaving a hole.

By my invention, as will hereinafter be fully described, I so constructthe needle and lever that the needle is held from upward movement during the rocking ot' the lever and when in position to hold the needlein inoperative position.

I will tirst describe the embodiment of my invention illustrated in theaccompanying drawings and then point out the invention in the claims.

In the drawings, Figure 1 is asectional view of needle, needle-leverembodying my invention, and a portion of cam-cylinder and portion ofneedle-ledge. Fig. 2 is a detail view of needle embodying my invention.

A is a portion of the cam-cylinder, and B the needle-ledge of thecharacter and construction described and illustrated in my Patent No.ASL (37, be't'ore spoken of.

C is a lover of the general character described in said patent, pivotedat w and having the tailpiece C for tilting it. This lever, as in myprevious patent, has the jaws c If, between which the shank/Z oi theneedle I), having the butt 1/, the hook 1/ and pivoted latch 1/,projects. In Fig. I I have shown the lever tilted, with the needle movedso that the butt is oti the ledge B and the needle supported by theshank resting on ledge/l in lever-jaw c.

In my improved construction the needlelever jaw 0* is provided with arectangular projection a and the needle with an inset w on the edge ofits shank portion. \Vhen the lever is tilted to the position shown inFig. 1, the projection w enters the inset I. and pushes the needles fromoil the ledge into inoperative position. The projection and ledge alsoooact in this movement and while the lever is in that position and inreturning to operative position to hold the needle from moving upward.

Having now fully described my invention, what I claim, and desire toprotect by Letters Patent, is-

I. In a knitting-machine, in combination, a needle, a pivotedneedle-lever in which said needle is loosely held and, by the movementof which, is adapted to be moved from operative to inoperative position,said needle being free to move vertically in the lever when in operativeposition, and means to hold the needle from upward movement during saidmovement of the lever from operative to inoperative position.

2. .In a knittii'ig-machine, in combination, a needle, a pivotedneedlelever in which said needle is loosely held and, by the movement ofwhich, is adaptedto be moved from operative to inoperative position andvice versa, and means to hold the needle from upward movement duringsaid movements of the lever from operative to inoperative position andvice versa.

In combination,a needle and pivoted needle-lever in which said needle isheld, the lever having a projection and the needle an inset normally outof contact and adapted to coact, in one position of the lever, to holdthe needle from moving upward.

4. A jaw needle-lever having a lateral projection from the upper portionof one of the aws.

5. In combination, aneedle and pivoted needle-lever in which the needleis loosely held, the needle having an inset and the lever a projection,adapted, on the tilting of the lever to move the needle, to coact withthe inset and hold the needle from vertical movement.

6. In combination, a needle and pivoted needle-lever in which saidneedle is held, the needle having an inset and the lever a projection,adapted, on the tilting of the lever to move the needle, to coact withthe inset and hold the needle from vertical movement during said tiltingand when in tilted position.

7. A needle having an inset in the edge of its shank portion.

8. A needle having a solid shank and an inset in the edge of said shank.

In testimony of which invention I have hereunto set my hand, atPhiladelphia, on this 21st day of May, 1904;.
